TO ALL. WHOM IT MAY CONCERN:

Be it known that we, NELSON PETERSON and GEORGE W. JONES, of Antioch,county of ContraCosta, State of California, have invented a new anduseful Spring-Hammer for Blacksmiths; and we do hereby declare thefollowing description and accompanying drawings are sufficient to enableany person skilled in the art or science to which it mostnearlyappertains to make and use our said invention without further inventionor experiment. I l: I 4

The nature of our invention is the construction of a spring-hammer forsmiths, and it has for its object the employment of a spring, eitherflat or spiral, by which the hammer is raised from the anvil, while, bya treadle conveniently situated, the smith can bring the hammer downwith any required degree of force.

, It also consists in so suspending or mounting the axis, on which itmoves, that the hammer can be easily turned to any portion of the anvil.By turning the hammer over, the toe or point may be used when necessaryTo'more fully explain our invention, reference is had to theaccompanying drawings, of which- Figure 1 is a side sectionaleleVatiQm'ta-ken through a: w, fig. 2.

Figure 2 is a plan.

Figure 3 is an end view.

Similar letters of reference in each of the figures indicate like parts.

Ais the head of the hammer, having the handle, B. This handle isencircled by a band at O, or supported by an equivalent device on theaxle,'D, which has its hearings on the pillow-blocks or boxes, E. Theseboxes rest on the strong frame, F, and are formed with a number ofrecesses, a a, for the axes, so that by allowing the axle to stand at anangle, the hammer can be made to strike any required part of the anvil,shown at G.

Between the frames F a strong wood or metal bar, H, extends, having aslot in the centre which holds firmly one end of the curved spring I.This spring is of steel, and suflicieutly stiff to raise and retain thehammer clear of the anvil, whatever may be its weight. I

The connection between the spring and the end of the hammer-handle ismade by a link or connecting-rod, J, 4

In front of this axis D, and below the handle, the connecting-link orchain, K, has one end fastened, while the other is fastened to thelever, L. This lever is hinged, as shown, and has the treadle M crossingit, and reaching to a point where it will be convenient for the foot ofthe smith, by which it is operated I A series of holes maybe arranged onthe handle, so that the link K may be attached at a greater or lessdistance, and vary the force of the blow.

The link J is attached to the end-of the hammer by a swivel or movableband, so that, if desired, the ham mer may be turned over, and the pointused. To do this, the link K must be disconnected from the handle, and,after turning, attached to theieye, m.

An arm or lever, N, extends back from the bar H, at each side, and has aslot, 0, at the end, through which a screw, P, passes, by which it canbe secured at any point. By moving this arm up and down, the bar H will'be turned slightly, and the tension of the spring is increased ordiminished.

Any size of hammer may be used by increasing the POWGJLOf the spring I,and the smith can easily operate it with his foot, thus dispensing witha helper.

Having thusdescribedour invention, what we claim as new, and desiretosecure by Letters Patent, is-- 1. The bar H, withits slotted lever N,screw P, and spring I, in combination with the link J and handle B,substantially as described. i Q 2. The bearings E, having the recesses aapt for supportingthc axle D, so as to allow the hammer to be used onany part of the anvil, substantially as described.

In witness whereof, we have hereunto set our hands andsea1s I g i NELSONPETERSON. [L. s.] i GEORGE W. JONES. [L. 5.]
